The Schedule referred to in these Letters Patent and making paxt of thesame.

To whom it 'may concern:

Be it known that I, J ons B.

but produce smoother, better, andmoreinished work;-

and

My invention consists in applying to the periphery of each roll one ormore pressure-rollers, which may be of cast-iron or' other suitablematerial. v

f Figure 1 is a transverse section through a pair o rolls, provided withmy improvement.

Figure 2 is a top view ofthe same. A is the lower, and B the upper of apair of rolls, auch as are customarily employed in the manufacture ofsheet-iron and steel.. y

These rolls may be composed, as usual, of cast-iron, carefully turnedofi' and polished, and be journall'ed in customary housings O. v y Therolls are kept free from scales, and reserved at a high polish, by meansof rollers D E, which may be made to press with any desired forceagainst the peof levers F or G, whose other extremities may either haveweight, or weights H, adjustable toward and from more temper-screws, J.The cleansing-rollers should be so arranged, relatively to the rolls, asnot to deposit their debris upon that paitf the sheet entering therolls.
